Maybe you are talking about the fitting used to connect it to the rail? Such a fitting is easily manufactured by running a metric tap into one side of a 1/4NPT coupling, and using a flat gasket to seal the faces.

As far as the fitting it was a special order for murph made by some machine shop as i understand. I searched all over in person and on the internet to find a fitting that would mate the ODD fuel rail fitting on the euro to a guage. I could not find one in all the A/N ctalogs etc. Murph provided this all in one and it works tremendously.
You may feel comfortable phucking with high pressure fuel connections on a hot engine but i don't. I also use this all the time not on occasion. To me i have the best available tool for a relatively simple function and that is special.

hi TV,
You're still talking about relatively small changes here...the question by Old & New was whether it is possible to make substantial diffrerences to fuelling over the whole range just by using the idle mixture screw :-)
i.e "correcting this air/fuel curve"

Hope your wife had a nice B-day!

Hi tv,
OK, I think we are in agreement. The idle mixture pot can pull the injector pulse at idle by +/-0.4mS and correspondingly less at higher rpm/load.
My wife's birthday ? Damm, I knew I forgot something ! Is this why she isn't talking to me ? :-)

Gentlemen, I was alluding to the adjustment screws on the Vortech SuperFMU.
tv, the WIKA gauge may be the best that you have seen, but it is not the best.
Regarding the fitting, Tim did not have one available when I purchased the kit (I was the first one to purchase the kit as offered here on the board). I spent a great deal of time providing feedback to him, and the fitting is one of the things I discussed with him. I have a feeling that your fitting is very similar to my fitting.
I found that having a fuel gauge in the engine compartment had limited usefulness... I ended up with an electronic fuel gauge inside the car - perhaps you have seen my hideously tacky gauge cluster mounted atop the pod at one of our local gatherings? The supercharged grey 89? It will be at the Fort Adams show in Newport, RI on October second, if you want to take a look. Which reminds me: Is there a thread on that upcoming event

my air/fuel stays pretty flat and slightly on the rich side.
how old is your lh?

tom, 1989 MAF is relatively new, though.
Does anyone have a spare SuperFMU I can borrow?
Is there any "safety high pressure bypass" in the fuel loop of an 89? It just levels off at ~85psi even though I can get >100psi static and am running a Bosch 044 pump. I just installed it with a new filter. It filled a half gallon jug in a *jiffy* when I flushed it.
